PHOTOGRAPH

                                 The first object we can call a photograph was produce in 1822 by the French inventor Joseph Nicephore Niepce. The process was not really practical, thought, it required an exposure of as long as eight hours. Niepce became bankrupt, and in 1829 went into partnership with the French artist Louis Jacques Mande' Dangnerre, who was also working on the process. Dangnerre improved it to such an extent that he usually is considered the inventor of photography.
